Here鈥檚 a structured English explanation for "2019 Slot 1 DI-LR" (Data Interpretation and Logical Reasoning), tailored for an Indian competitive exam context (e.g., LSAT, CLAT, or similar tests):
2019 Slot 1 DI-LR: Solution Guide
Section Overview
This section typically includes 4-5 Data Interpretation (DI) questions followed by 5-6 Logical Reasoning (LR) questions, testing analytical and critical thinking skills. Focus on accuracy and speed.
Data Interpretation (DI) Tips
Skim First:
Read charts/tables/diagrams first to identify key variables (e.g., sales, population, percentages).
Note units (e.g., 鈧?crores, % growth).
Type of DI Questions:
Caselet Analysis: A paragraph followed by tabular data (common in Indian exams).
Line Graphs: Compare trends over time (e.g., quarterly revenue).
Pie Charts: Proportions (e.g., market share by company).
Example DI Question:
Q: A pie chart shows the percentage of students in Class 10 from three schools (A, B, C). A table lists pass percentages for each subject. Which school has the highest overall pass rate?
Solution:
Calculate total passes per school: (Total students 脳 Pass %).
Compare results. School B leads (30 students 脳 85% = 25.5 vs. School A: 25 脳 80% = 20).
Logical Reasoning (LR) Strategies
Syllogisms:
Use Venn diagrams to map premises (e.g., "All birds are animals. Some birds are penguins. Therefore...").
Common patterns:
Converse Error: Assuming "If P then Q" implies "If Q then P."
Excluded Middle: Failing to account for "neither P nor Q."
Seating Arrangements:
Draw a grid or circle diagram.
Use keywords: Left/right, Directly/Across, Not Adjacent.
Puzzles (Blood Relations, Odd Man Out):
Blood Relations: Create family trees for complex kinship questions.
Odd Man Out: Compare attributes (age, gender, occupation) to identify exceptions.
Example LR Question:
Q: Six friends (A-F) sit in a row. A and B are adjacent. C is not next to D. E is at one end. Who sits in the middle?
Solution:
E must be at position 1 or 6.
A and B occupy consecutive seats (e.g., 2-3 or 4-5).
C and D avoid adjacency 鈫?Middle seat (position 4) is free. Answer: Position 4 is empty or occupied by F.
Common Pitfalls
DI: Misreading units (e.g., lakhs vs. crores) or misinterpreting percentages.
LR: Overlooking negation (e.g., "None" vs. "Some") or misapplying syllogistic rules.
Time Management
DI: 20-25 minutes for 5 questions.
LR: 30-35 minutes for 8 questions.
Practice resource
For similar questions, refer to past LSAT India papers or CLAT mock tests focusing on DI-LR clusters. Use online tools like V鐗瞭us or Testbook for timed practice.
